Need Help!- MR-S3 3 axis drive

[zsbojtos]

Hi everybody,

We have a Mitsubishi MR-S3-80AA-E-01 drive (3 axis). One of them is went wrong. I found the problem on it, the current measure part (DK-431, BKO-NC2046).

Does anybody know where can I get it (new or used) ?

Thanks Zsolt

thanks,steve

I found same company on the web. They want to buy!!! not sell.

The 5v voltage regulator, fastened to the 1 inch tall heat sink is probably a 7805. 7805ct is rated at 1.5 amps. These are very cheap on ebay. I have changed to one of these which did not fix the problem but also did not give a new alarm.
